Pre-built or self build

Hi folks

Looking at investing in a gaming PC for 1080p gaming. Not looking to spend more than €600-700ish so looking at Ryzen builds. Recently noticed on HUKD a lot of pre-built machines from CCL, AWD which seem to offer great value compared to getting the parts separate. Question is, is this correct or am i just looking in the wrong places for parts.

Build of one i'm looking at is below, can i get this cheaper elsewhere? HUKD suggests no but wondering if that is correct. If so do any of you have any recommendations of changes to the below build, PC can be customised by following the link below.

AMD Ryzen 5 2600x 3.6GHz Hexa Core
Stock Cooler
Asus Prime B350-Plus
Corsair Vengeance LPX 16GB (2x8GB) 3000mhz DDR4
Gigabyte 240GB 2.5" SATA III SSD
No HDD (have a 500gb one spare and will invest in a 2TB at some stage)
MSI Radeon RX 580 ARMOR 8GB Graphics Card
Edimax PCI Wi-Fi
Corsair VS Series VS550 550W 80+ Bronze PSU
Aero Cool Bolt Mid Tower Gaming Case Black

Consider upgrading motherboard to MSI B450 - lets you use a thing called StoreMI to fuse the HDD & SSD into a single Windows partition.
Definitely upgrade GPU to GTX 1660.

I'd also add another 120mm fan (£4).
